kubernetes-dashboard - 恢复 kubernetes-dashboard pod？

问题描述

我已经在 Ubuntu 18.04.5 LTS (Bionic Beaver) 上安装了 kubernetes。现在尝试运行 kubernetes-dashboard。然而它一直在崩溃。

NAME                                         READY   STATUS             RESTARTS   AGE

我错过了什么或如何从中恢复？

解决方案

尝试以下

  • 检查kubectl get svc | grep kubernetes然后kubectl describe svc kubernetes- 如果这里有任何问题，请更正它。

  • 定义主机名/etc/hosts

#vim /etc/hosts
YOUR_IP HOSTNAME
  • 禁用防火墙
  • 重启 Kubelet
  • 重启 Docker
  • 刷新 IP 表
